Maintaining Libraries for External Methods and Functions
The Library Browser enables you to view and maintain the libraries for your current schema. You can use the libraries, which store your external user-written Application Program Interface (API) calls, to import both external methods and external functions, if required.
You must create a library for your external routines before you can define external methods or external functions for the API entry points.
Only one Library Browser window can be open at any time.
To open a Library Browser window
-
Select the Libraries command from the Browse menu
The Library Browser is then opened. The Library Browser is displayed in the form specified by your Browser options; that is, it is user-specific. You can change your default browser options, if required, by using the Browser sheet from the Options menu Preferences command.
The Jade default display of the Library Browser is as follows.
